   I got mine to have an intermediate focus, sometimes the gap between   
   near and far annoyed me. Looking at stuff on tables like at computer   
   shows was a problem, either too near or too far. My blended vision   
   glasses  had the same narrow area of close vision correction, so I   
   quit using them.   
      
   Trifocals had a different problem, two areas would be almost within   
   range, I tended to jump between them.  Back to plain old bifocals.
